To all whom it may concern; g 1 .Be it known that I,YELZY R. WIiLIAMS, acitizen of the United States, residing-at "St. Joseph, inthe county ofBuchanan and State of Missouri, have invented a certain new and usefulImprovement in Trigger Mechanisms, of which the following is aspecification. l My invention relates to improvements'in triggermechanisms. M i i One of the Objects of my invention is to provide atrigger mechanism, of the type havlnga main trigger and an auxiliary ori hairtrigger; which is reliable in operation, which is easily operated,which is not liable togetout of order, and which may bereadilyapplied tofire-arm's now in use. v Y -The'novel features of my inventionarehereinafter fully describedand claimed.

In the accompanying drawings, which illlllstftte thepreferred embodimentof my inve tion, as applied to afir'e-arm having a sliding hammer, v H"Flgure 1 is a side elevation ofa portion 5 of a fire arm which isprovided with my i improvement. s s

In this View,theparts cona. trolledby the auxiliary trigger are shown in the releasedposition. i i

The upper end of the plate 5 is provided with a slot in which is mountedan auxiliary releasing member, preferably comprising a releasing lever9, which is'pivoted to "the plate 5 by a' tran'sversepin 10.Thereleasing lever 9 carries a transverse pin 11 on which is'mounted africtionroller 12,which is adapted to strike against an abutmentcomprising a fixed part 13 of the fire-arm,
